How to Dry Pillows in Dryer

Can You Dry Pillows in the Dryer?

Yes — most pillows can be dried in a tumble dryer, and it's actually the recommended method for many pillow types. The key is using the right heat setting, adding dryer balls to prevent clumping, and making sure the pillow is completely dry before putting it back on the bed. A pillow that's damp inside is a breeding ground for mold and dust mites.

Which Pillows Can Go in the Dryer?

Polyester fiberfill pillows: Dryer-safe on low to medium heat — the most forgiving type
Down and feather pillows: Dryer-safe on low heat with dryer balls — require the most care to prevent clumping
Down alternative pillows: Dryer-safe on low heat
Memory foam pillows: Do NOT put in the dryer — heat breaks down the foam. Air dry only.
Latex pillows: Do NOT put in the dryer. Air dry flat.

Always check the care label before drying. When in doubt, use the lowest heat setting available.

What You'll Need

A large-capacity dryer (pillows need room to tumble freely)
Dryer balls or clean tennis balls (essential for preventing clumping)
A large mesh laundry bag (optional but protects the pillow cover)

The Handy Laundry Wool Dryer Balls (Pack of 6) are ideal for pillows — use all six at once to maximize agitation and break up clumps as they form. They also reduce drying time by improving airflow in the drum.

For extra protection, place the pillow inside the Tenn Well Extra Large Mesh Laundry Bag (43 x 35 inch) before putting it in the dryer. This protects the pillow cover from snagging and keeps the fill contained if a seam opens.

Step-by-Step: How to Dry Pillows in the Dryer

Check the care label: Confirm the pillow is dryer-safe and note the recommended heat setting.
Dry two pillows at once: This balances the drum load and allows the pillows to tumble against each other, which helps break up clumps. Drying a single pillow can cause the drum to become unbalanced.
Add 4–6 dryer balls: Place them in the drum with the pillows. These are non-negotiable for down and fiberfill pillows.
Set to low heat: Low or medium heat is safer for all pillow types. High heat can melt synthetic fibers and damage down clusters.
Run a full cycle (60–90 minutes): Pillows take longer to dry than clothes. The outside may feel dry while the center is still damp.
Check and fluff manually: Pause the dryer every 20–30 minutes, remove the pillows, and squeeze them firmly. Break up any clumps you feel, then return to the dryer.
Run additional cycles: Most pillows need 2–3 dryer cycles to dry completely. This is normal — don't rush it.
Do the squeeze test: The pillow is fully dry when it springs back immediately after being squeezed and feels uniformly light and fluffy with no dense damp patches.

How to Tell If a Pillow Is Fully Dry

This is the most important step. Press your hands firmly into the center of the pillow — if you feel any cool, dense, or heavy patches, the inside is still damp. A fully dry pillow feels uniformly light and springs back quickly when compressed.

Never put a pillow back on the bed until it passes this test. A damp pillow develops mold within 24–48 hours, which is a serious health concern and will ruin the pillow.

Drying Pillows Without a Dryer

If you don't have a dryer, pillows can be air dried but it takes significantly longer:

Lay flat on a clean surface or drying rack in a warm, well-ventilated room
Flip every few hours and squeeze to redistribute the fill
Place a fan nearby to speed up drying
Expect 6–12 hours or more — and do the squeeze test before using

Air drying is not recommended for down pillows as it's very difficult to prevent clumping without mechanical agitation.

How Often Should You Wash and Dry Pillows?

Most pillows should be washed every 3–6 months. Washing removes sweat, skin cells, and dust mites that accumulate over time. Always dry thoroughly immediately after washing — never store a washed pillow until it's completely dry.

Frequently Asked Questions

Why do my pillows clump after drying?

Clumping happens when the fill (down or fiberfill) sticks together as it dries without being broken up. The solution is dryer balls — use 4–6 and pause the dryer every 20–30 minutes to manually fluff the pillow.

Can I dry a memory foam pillow in the dryer?

No — heat breaks down memory foam. Air dry memory foam pillows flat in a well-ventilated room. They take 6–12 hours to dry fully.

My pillow smells after drying — what went wrong?

The pillow likely wasn't fully dry before being stored or used. Rewash and dry thoroughly, doing the squeeze test before putting it back on the bed. Add a cup of white vinegar to the wash cycle to neutralize odor.

Can I dry two different types of pillows together?

It's better to dry similar types together. Down pillows and polyester pillows have different heat requirements. If you must mix them, use the lowest heat setting appropriate for the most delicate pillow.
